  3. Bushings replaced with Northern Tool bearings?

    Can the provided bushings in #50839 wheel/tires be removed and Northern Tool part #13672, or #13682 bearings be installed in their place?

    1. I used a long punch to remove the bushings from the wheel since the size I needed was 1/2 inch. I then purchased sealed flanged bearings and removed the inner seal before install. I used a 1/2 drive socket and an extension to install the new bearings worked fine you don't need to spend money on special tools. Hope this helps.
